process.mainModule.filename Deprecated

The process.mainModule.filename property in Node.js is deprecated and should not be used in modern code. This property used to provide information about the entry point module filename.

As of Node.js version 14, the developers have decided to deprecate this property because it poses several security risks and it is not reliable in certain scenarios.

It is strongly recommended to use alternative methods to obtain the filename of the main module. One common approach is to use the __filename global variable, which provides the absolute path of the current module file. Here is an example of how to use __filename:

    const path = require('path');
    console.log(__filename);
  

This will output the absolute path of the current module file.

Alternatively, if you need to retrieve the directory name of the main module file, you can use the __dirname global variable. Here is an example:

    const path = require('path');
    console.log(__dirname);
  

This will output the absolute directory path of the current module file.
